1:246 Gearbox with mount and shaft for DC motor

Remix of https://www.thingiverse.com/thing:7390 by emmett

I wanted to see if this gearbox can be driven by a small 3-6V DC-motor. So I rebuild the sun gear for a 2mm motor shaft.
I works if you got the gearbox running smoothly. However, even with this ratio, you cannot really move something with it.

I also added some mounts (use M4 screws) and a security ring so the top doesn't fall off.
